The 40V max XGT® Brushless 8-1/2” Dual-Bevel Sliding Compound Miter Saw Kit (GSL02M1) provides 4,800 RPM for faster and smoother cutting. The rail-forward design maximizes workspace when the miter saw is positioned flush against a wall. The miter saw has a large 2-3/4” x 12-1/4” cutting capacity at 90-degrees. The saw miters 0° to 60° left and right and bevels from 0° to 48° (left and right). The efficient brushless motor runs cooler and more efficiently for longer tool life. The GSL02M1 features Automatic Speed Change™ technology to adjust cutting speed and torque under load for optimum performance and a soft start to suppress start-up reaction for smooth start-ups and longer gear life. Extension wings all for cutting longer materials and retract for easier storage. An electric brake provides maximum productivity. For improved efficiency, it is equipped with Auto-start Wireless System technology. AWS® utilizes Bluetooth® technology for wireless communication between the tool and dust extractor (sold separately). When the trigger of the AWS-equipped GSL02M1 is engaged, the AWS-equipped dust extractor powers-up. When the trigger is released, the dust extractor powers-down. AWS is intelligent communication that eliminates cords and excessive noise since the dust extractor runs only when the tool is running. XGT is a system of equipment, tools, batteries and chargers utilizing 40v max lithium-ion batteries. XGT is engineered to deliver high power to take on high-demand applications, allowing users to completely transition to a cordless job site. XGT is equipped with advanced brushless motor engineering, intelligent digital communication, and superior durability features to outpower, outsmart and outlast the rest.
